The lower Bollinger Band equals the 20-period Simple Moving Average minus two standard deviations of recent closes. on the Weekly chart, the 20-bar window spans roughly 100 minutes of trading. Because standard deviation scales with actual price volatility, the band automatically adjusts: high-volatility stocks require bigger moves to break below, low-volatility ones do not. The screen does not require a fresh cross below the band; any current close below the level qualifies. With 59 stocks matching, the count reflects normal intraday range behavior across the full universe of top US equities.
Below Lower Bollinger is ambiguous by design — the same condition can mark a selling climax or accelerating distribution, and the trade direction depends on context. In calm, liquid names without news, a close below the lower band often snaps back quickly as algorithmic buyers step in at a statistical value level. In stocks with active negative catalysts, the lower band can be a station in a longer move down, not a reversal point. The failure mode for long trades is the latter: buying statistical value that turns out to be a fundamentally repriced level. The failure mode for short confirmation is a mechanical bounce that stops out a short entry immediately. Intraday traders most commonly use this screen as an alert system rather than a direct entry, then apply volume, time-of-day, and higher-timeframe trend context. For the inverse, see Above Upper Bollinger. For compound oversold confirmation, RSI Oversold Extreme can layer over this signal.
